This paper has systematically discussed an easy way to determine observation parameters of navigation-based GPS and, through test and research on absolute position precision and relative position precision, discovered the fact that the observation parameter determination plays a leading role in navigation-based GPS positioning. It is considered that the setting up of correct observation parameters seems to be an important means for precision improvement of navigation-based GPS single point positioning.
